Why? Most late boarders follow the leader towards the back of the plane to find seats. When they find none, they start heading forward and are instructed to take the first available seat. So there are times that late boarders fill up middle seats from the back to the front of the plane. Some late boarders are astute enough to grab a middle seat up front. I've noticed fewer of them than those mentioned in the preceeding paragraph. Agree @dfwskier the front third of the plane is Southwest's "hidden first class" likely to have an open middle - IMO because the bin space fills up so those late boarders with carry-on keep heading to the back and once they find bin space they take the next available seat as they head forwards. On a moderately full plane then good chance for an open middle seat in the way back as well.
